LM4250J-MIL – Op-Amp – Texas Instruments

The LM4250J-MIL is a Texas Instruments programmable single-channel micropower operational amplifier in an 8-pin ceramic CDIP (J) package, rated for the -55C to +125C military temperature range. A single external resistor sets bias current, slew rate, gain-bandwidth, and noise.

The LM4250J-MIL from Texas Instruments (originally a National Semiconductor design) is a programmable monolithic micropower operational amplifier housed in a rugged 8-pin ceramic dual-in-line (CDIP-8 / J) package and screened for the full military temperature range of -55C to +125C. What sets the LM4250 family apart is its single-resistor programmability: one external set resistor lets the designer trade off quiescent current, slew rate, gain-bandwidth product, and input noise to match the exact power budget of the application. This makes the LM4250J-MIL an excellent choice for battery-powered, long-life, and power-constrained analog designs.

Operating across a wide +/-1V to +/-18V supply range, the LM4250J-MIL can be biased to draw as little as a few microwatts and enter standby at power levels as low as 500 nW, all while retaining usable amplifier performance. It requires no external frequency compensation, offers offset-null capability, and includes output short-circuit protection, simplifying board design in demanding environments.
